A6 c8 30L Quattro diesel

[Charliie]

I have a6 30l c8 that started dying on me the other day and took it to the garage and they said the battery is not charging on it said it’s the alternator. The car has only got 68000  on it. I was just wondering if anybody else has had this issue. Pls help? Could it be something else? My first error message before it died was⬇️ just sceptical changing it because there like £2000 just for part

68000 miles is perhaps a little earlier than expected for an alternator to expire, but not unreasonably so. Get the garage to test the battery when you change the alternator as it may have been damaged by continual discharge.

However look at another recent topic on this forum regarding "brake servo restricted" for further enlightenment.

When the car is running, the batteries only chucking out 12.2 V that’s why I think is the alternator

[cliffcoggin]

I am not disagreeing.

What is trying to be said here Charlie is that it seems (in caps) that the alternator is at fault, but I would get an independent check on this before taking action. I fully agree with what Cliff is trying to reinforce - don’t assume the battery isn’t sub standard as well - until that has also been tested.

If it were mine, I would investigate the route to getting your alternator repaired if found to be faulty. 
Kind regards,

Gareth.

I had the brake servo restriction fault not long ago, if the codes the same as mine it’s the pressure sensor  near the brake servo! 
mine was intermittent would go away after turning off and engine the back on !

what other people have said is if fault stays on the ABS pump  then takes over braking and that it can get damaged if driven over long distances . By the looks of it in other forums it’s common fault across all Audi’s

The pressure sensor is about £94 from Audi parts . Audi changed mine under the all in warranty. Hope this helps 

also mine seem to throw up the fault when stop start kicked in so I would switch it off straight away after starting the engine .

Why? A wise man once opined to me that what man has made, man can repair.
